-/**\r
- * @class Ext.Direct\r
- * @extends Ext.util.Observable\r
- * <p><b><u>Overview</u></b></p>\r
- * \r
- * <p>Ext.Direct aims to streamline communication between the client and server\r
- * by providing a single interface that reduces the amount of common code\r
- * typically required to validate data and handle returned data packets\r
- * (reading data, error conditions, etc).</p>\r
- * \r
- * <p>The Ext.direct namespace includes several classes for a closer integration\r
- * with the server-side. The Ext.data namespace also includes classes for working\r
- * with Ext.data.Stores which are backed by data from an Ext.Direct method.</p>\r
- * \r
- * <p><b><u>Specification</u></b></p>\r
- * \r
- * <p>For additional information consult the \r
- * <a href="http://extjs.com/products/extjs/direct.php">Ext.Direct Specification</a>.</p>\r
- * \r
- * <p><b><u>Providers</u></b></p>\r
- * \r
- * <p>Ext.Direct uses a provider architecture, where one or more providers are\r
- * used to transport data to and from the server. There are several providers\r
- * that exist in the core at the moment:</p><div class="mdetail-params"><ul>\r
- * \r
- * <li>{@link Ext.direct.JsonProvider JsonProvider} for simple JSON operations</li>\r
- * <li>{@link Ext.direct.PollingProvider PollingProvider} for repeated requests</li>\r
- * <li>{@link Ext.direct.RemotingProvider RemotingProvider} exposes server side\r
- * on the client.</li>\r
- * </ul></div>\r
- * \r
- * <p>A provider does not need to be invoked directly, providers are added via\r
- * {@link Ext.Direct}.{@link Ext.Direct#add add}.</p>\r
- * \r
- * <p><b><u>Router</u></b></p>\r
- * \r
- * <p>Ext.Direct utilizes a "router" on the server to direct requests from the client\r
- * to the appropriate server-side method. Because the Ext.Direct API is completely\r
- * platform-agnostic, you could completely swap out a Java based server solution\r
- * and replace it with one that uses C# without changing the client side JavaScript\r
- * at all.</p>\r
- * \r
- * <p><b><u>Server side events</u></b></p>\r
- * \r
- * <p>Custom events from the server may be handled by the client by adding\r
- * listeners, for example:</p>\r
- * <pre><code>\r
-{"type":"event","name":"message","data":"Successfully polled at: 11:19:30 am"}\r
-\r
-// add a handler for a 'message' event sent by the server \r
-Ext.Direct.on('message', function(e){\r
- out.append(String.format('<p><i>{0}</i></p>', e.data));\r
- out.el.scrollTo('t', 100000, true);\r
-});\r
- * </code></pre>\r

+ * @class Ext.Direct
+ * @extends Ext.util.Observable
+ * <p><b><u>Overview</u></b></p>
+ *
+ * <p>Ext.Direct aims to streamline communication between the client and server
+ * by providing a single interface that reduces the amount of common code
+ * typically required to validate data and handle returned data packets
+ * (reading data, error conditions, etc).</p>
+ *
+ * <p>The Ext.direct namespace includes several classes for a closer integration
+ * with the server-side. The Ext.data namespace also includes classes for working
+ * with Ext.data.Stores which are backed by data from an Ext.Direct method.</p>
+ *
+ * <p><b><u>Specification</u></b></p>
+ *
+ * <p>For additional information consult the
+ * <a href="http://extjs.com/products/extjs/direct.php">Ext.Direct Specification</a>.</p>
+ *
+ * <p><b><u>Providers</u></b></p>
+ *
+ * <p>Ext.Direct uses a provider architecture, where one or more providers are
+ * used to transport data to and from the server. There are several providers
+ * that exist in the core at the moment:</p><div class="mdetail-params"><ul>
+ *
+ * <li>{@link Ext.direct.JsonProvider JsonProvider} for simple JSON operations</li>
+ * <li>{@link Ext.direct.PollingProvider PollingProvider} for repeated requests</li>
+ * <li>{@link Ext.direct.RemotingProvider RemotingProvider} exposes server side
+ * on the client.</li>
+ * </ul></div>
+ *
+ * <p>A provider does not need to be invoked directly, providers are added via
+ * {@link Ext.Direct}.{@link Ext.Direct#add add}.</p>
+ *
+ * <p><b><u>Router</u></b></p>
+ *
+ * <p>Ext.Direct utilizes a "router" on the server to direct requests from the client
+ * to the appropriate server-side method. Because the Ext.Direct API is completely
+ * platform-agnostic, you could completely swap out a Java based server solution
+ * and replace it with one that uses C# without changing the client side JavaScript
+ * at all.</p>
+ *
+ * <p><b><u>Server side events</u></b></p>
+ *
+ * <p>Custom events from the server may be handled by the client by adding
+ * listeners, for example:</p>
+ * <pre><code>
+{"type":"event","name":"message","data":"Successfully polled at: 11:19:30 am"}
+
+// add a handler for a 'message' event sent by the server
+Ext.Direct.on('message', function(e){
+ out.append(String.format('<p><i>{0}</i></p>', e.data));
+ out.el.scrollTo('t', 100000, true);
+});
+ * </code></pre>
+ * @singleton
